I got the E_AUTH_BAD_DEVICE_KEY error so I followed this
Somehow my digital editions key disappeared from my Keychain Access. How do I get it back? I have tried to reinstall adobe editions 4.5 and 4.0 and I have tried to remove the activation.dat file /Users//Library/Application Support/Adobe/Digital Editions.
Anyone know how to get it back?
Close all applications.
Press WINDOWS + R.
In the Open text box, type regedit and then press Enter. The Registry Editor opens.
In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept
Remove the Adept Folder.
In the Confirm Key Delete dialog, click OK.
Close the Registry Editor.
Open Adobe Digital Editions and reauthorize..
quit Adobe Digital Editions.
Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
If you are using 10.7, see https://helpx.adobe.com/x-productkb/global/access-hidden-user-library-files.html
Open Adobe Digital Editions and reauthorize.
